How are npn and pnp types of transistors different?

Options

  1. AIn the number of layers they have
  2. BIn the type of charge carriers they use
  3. CIn their ability to convert light energy
  4. DIn the arrangement of their layers

Correct answer

D. In the arrangement of their layers

Step-by-step solution

npn and pnp types of transistors differ in the arrangement of their layers, with one having two layers of n-type semiconductor and one layer of p-type semiconductor, while the other has two layers of p-type semiconductor and one layer of n-type semiconductor.
